ABSTRACT

A pull handle for dispenser machines having a first arm and a second arm. The second arm may be articulated and translated about an axis. The joint between the first and second arms is configured such that the second arm may be secured into and released from a first position. The first position facilitates accessible engagement of the pull handle.

BACKGROUND OF THE INVENTION

[0001] Pull handles have been used for many years to dispense retailproducts from a variety of dispensing machines. One type of dispensingmachine has a slot for depositing coins or other currency and a pullhandle directly connected to a dispensing mechanism. A deposit of theappropriate amount of currency permits the handle to be pulled,dispensing one or more products to the user. Multiple pull handles maybe used on one dispensing machine to provide access to a selection ofproducts. The front panel or door of the machine typically swings openon a vertical hinge to provide access to the interior of the machine forrestocking and withdrawal of deposited currency.

[0002] One type of prior art pull handle is a one-piece handle 100having a knob 110 integrally connected to the end of a shaft 120, shownin FIG. 1. The door 130 has a small opening 140 surrounding the shaftsuch that the opening passes over the shaft and knob when the door isswung open, attached to the machine by a vertical hinge. The pull handleextends through a cover plate 150 which occupies the space in theopening around the pull handle when the door is closed. One disadvantageto the prior art handle is that the knob must be small in order to passthrough the opening in the door. Due to the small surface area on therear side of the knob and the short distance between the knob and thedoor, it is difficult to grab and pull the handle in a perpendiculardirection away from the door. Furthermore, the prior art handle fails tocomply with the requirements of the American with Disabilities ActAccessibility Guidelines (ADAAG), specifically section 4.27.4 onControls and Operating Mechanisms, which requires operating mechanismsto be operable with one hand and shall not require tight grasping,pinching or twisting of the wrist. Accordingly, there is a need for animproved pull handle that allows easy access to the interior of thedispensing machine, can be pulled easily without digital engagement, andcomplies with the requirements of the American with Disabilities Act.

[0003] The present invention satisfies one or more of the above needs.

SUMMARY OF THE INVENTION

[0004] The present invention is embodied in a dispensing machine havinga housing, a dispensing mechanism at least partially within the housing,a door, the door defining an opening, and a pull handle. In oneembodiment, the pull handle may be engaged without digital engagement orgrasping or pinching the handle. In another embodiment, the pull handlehas two arms that permit the dispensing machine door to be opened. Thepull handle may be coupled to a dispensing mechanism for dispensingproducts from a vending or dispensing machine. In an embodiment, thepull handle includes a first arm having a proximate end and a distalend, and a second arm having one end pivotally coupled to the distal endof the first arm such that the second arm may pivot about a first axisat the distal end of the first arm, wherein the second arm may besecured in a first position forming a first angle with the first arm andthe second arm may be released to a second position forming a secondangle with the first arm. The proximate end of the first arm may beconfigured to be pivotally coupled to a dispensing mechanism such thatthe first arm may pivot about a second axis at a location where thefirst arm may be coupled to the dispensing mechanism.

[0005] In one embodiment, the second arm may be secured in the firstposition by a fastener and surfaces of the first arm juxtaposed againstsurfaces of the second arm. The second arm may also be translated in aradial direction.

[0006] The pull handle may further include a fastener coupled to thedistal end of the first arm, and at least one slot protruding throughthe coupled end of the second arm for coupling the second arm to thefirst arm such that the second arm may be rotated and translated aboutthe fastener. The second arm may be translated in a radial direction tobe released and rotated to the second position.

[0007] In another embodiment, the first arm of the pull handle, in thefirst position, may form an approximately 90 degree angle with thesecond arm, and in the second position, the first arm may form anapproximately 180 degree angle with the second arm. The dimensions ofthe first arm and second arm may be configured such that the pull handlemay be engaged without grasping and/or without digital engagement of thepull handle.

[0008] In another embodiment of the dispensing machine, when the pullhandle is in the first position, the second arm forms a first angle withthe first arm, the fastener is located in a distal end of the slots, afirst side of each of the two teeth of the second arm is adjacent to thedistal end of the first arm, a proximate end of each of the two teethhas a curved portion, and the second arm may be translated in a radialdirection to the second position by the fastener traveling in the slots.In the second position, the second arm forms the first angle with thefirst arm, the fastener is located in a proximate end of the slots, thefirst side of each of the two teeth is adjacent to the distal end of thefirst arm, and the curved portion is located proximate to the distal endof the first arm such that the curved portion may slide adjacent to thedistal end of the first arm, permitting the second arm to moverotationally about the fastener, about the first axis, to the thirdposition. In the third position, the second arm forms a second anglewith the first arm, and the fastener is located in the proximate end ofthe slots.

DETAILED DESCRIPTION

[0021] A pull handle 20 embodying the features of the present inventionis shown in FIGS. 2-5. The pull handle 20 is configured to be attachedto a dispensing mechanism. Dispensing mechanisms are well known in theart, typically having a rod or lever which, in response to a userinitiated motion, will release a product to the user.

[0022] The pull handle 20 includes a first arm 22, a second arm 24, anda fastener 26 used to couple the first and second arms forming aconjoined handle. One end of the first arm may be configured forattachment to a dispensing mechanism. The end configured for attachmentto the dispensing mechanism may be considered the proximate end 28 ofthe handle. Accordingly, the first arm has both a proximate end 28 and adistal end 30, and the second arm has both a proximate end 32 and adistal end 34.

[0023] The embodiment illustrated in FIGS. 2-5 depict the first arm 22and the second arm 24 formed of generally rectangular, cubed shaftshaving ends configured for attachment to each other and to a dispensingmechanism. The distal end 30 of the first arm 22 is coupled to theproximate end 32 of the second arm 24 using a fastener 26 such as ascrew, rivet, pin, bolt, or other suitable means for coupling the twoarms.

[0024] With reference to FIGS. 4-5, the general shape of the arms willbe described. The proximate end 28 of the first arm 22 is provided witha horizontally extending notch 36 that creates a top tooth 42 and abottom tooth 44, the top and bottom teeth are spaced apart from eachother, each having a hole 46 protruding through the tooth 42, 44. Thehole 46 is configured for receiving a fastener to couple the first armto a dispensing mechanism (not shown). The teeth preferably have theshape of generally flat, rectangular planks. The proximate end 28 of thefirst arm 22 may be configured to receive an end of the dispensingmechanism into the notch 36 and be secured in place with a fastenerextending through the top tooth 42, the end of the dispensing mechanism,and the bottom tooth 44. The notch 36 and fastener may be configuredsuch that the first arm 22, and therefore, the entire pull handle 20,may pivot around a vertical axis A which runs through the holes in thetop and bottom teeth 42, 44. The notch 36 may be of any suitable shapeand may include protruding teeth or walls to limit the range withinwhich the first arm 22 may pivot.

[0025] The distal end 30 of the first arm 22 is adapted with a tooth 48extending longitudinally beyond the main body of the first arm 22. Thetooth 48 is oriented in a position generally perpendicular to the toptooth 42 and bottom tooth 44 at the proximate end 28 of the first arm22. The tooth 48 may include a hole configured to receive a fastener forcoupling the second arm 24 to the first arm 22. The distal end 30 of thefirst arm 22 also includes two distal faces 49, one located on each sideof the tooth 48.

[0026] The second arm 24 is adapted with a longitudinally extendingnotch 54 formed at the proximate end 32 of the second arm 24. The notch54 creates a first side tooth 56 and a second side tooth 58 at theproximate end 32 of the second arm 24. The notch also creates aproximate face 59 between the first side tooth 56 and the second sidetooth 58. The teeth 56, 58 each have a slot 60 extending through thetooth. Each slot 60 is generally circular-oblong oriented such that theslot 60 is elongated in a direction parallel to a longitudinal axis ofthe second arm 24, the longitudinal axis extending through the proximateend 32 to the distal end 34 of the second arm 24. Each tooth is similarin shape. The proximate end of each tooth curves gradually to tapertoward the proximate end 32 of the second arm 24.

[0027] With reference now to FIG. 2, second arm of the pull handle 20 isshown secured in a dispensing position. The tooth 48 of the first arm 22and the first and second side teeth 56, 58 of the second arm 24 areconfigured to be slidably coupled such that the tooth 48 of the firstarm 22 is disposed between the first and second side teeth 56, 58 of thesecond arm 24. The first and second arms 22, 24 are linked by thefastener 26 that extends through the slot 60 of the first side tooth,the singular tooth 48, and the slot of the second side tooth 58. Thesecond arm 24 is moveable about a fastener axis B of the fastener 26.The second arm 24 may be rotated about the fastener axis forming aplurality of angles with the first arm 22. Additionally, the second arm24 may also be translated radially to and away from the fastener axis Bby way of the slots 60 in the second arm 24. The second arm 24 is shownin a first slot position in FIG. 2 where the fastener 26 is located at adistal end of the slot 62. The second arm may be translated in a radialdirection such that the arm 24 travels over the fastener 26 until thearm is in a second slot position. FIG. 3 shows the second arm 24 in thesecond slot position where the second arm 24 is positioned such that thefastener 26 is located at a proximate end of the slot 64.

[0028] With reference now to FIG. 2, when the second arm 24 is in thedispensing position, the arm 24 is in the first slot position and willmaintain this generally secured dispensing position against anynon-radial force on the arm 24. The second arm 24 is secured in thisposition by a combination of forces and juxtaposition of parts betweenthe first and second arms 22, 24. The proximate face of the second arm24 abuts the top portion of the singular tooth 48 of the first arm 22.Simultaneously, the top, flat portions of the first and second sideteeth 56, 58 of the second arm 24 abut the two distal faces 49 of thefirst arm 22. Where the second arm 24 is in the first slot position, thecurved portions of the first and second side teeth 56, 58 arepredominantly below the edge of the first arm 22. While in the firstslot position, the abutting surfaces, together with the fastener 26contacting the slot 64 of the second arm 24, prevent the second arm 24from rotating when tangential force is applied to the arm 24. Theabutting surfaces of the first arm 22 can be generally flush with thesurfaces of the second arm 24. The abutting surfaces, illustrated asbeing generally flat surfaces, may be rough, notched, slotted, or of anyother designed configuration that may increase the friction between thefirst and second arms or assist in maintaining the second arm 24 in thedispensing position.

[0029] The second arm 24 is articulated from the dispensing position toan access position by way of a movement to an intermediate position whenthe second arm 24 is in the second slot position. With reference now toFIG. 3, the second arm 24 is shown in the intermediate position wherethe second arm 24 is in the second slot position. The second arm may betranslated in a direction toward the distal end 34 of the second arm 24.Consequently, the fastener passes through the slots 60 in the first andsecond side teeth 56, 58 from the distal end of the slots 62 to theproximate end of the slots 64. In this intermediate position, distanceis created between the proximate face 59 (shown in FIG. 5) of the notchof the second arm 24 and the top portion of the tooth 48 of the firstarm. Simultaneously, the curved portions of the first and second sideteeth 56, 58 are proximate to the two distal faces 49 of the first arm22. The distance between the proximate face 59 and the singular tooth48, together with the curved first and second side teeth 56, 58, permitthe second arm 24 to pivot about the fastener axis B. While thejuxtaposition of flat surfaces in the dispensing position and the topsof the first and second side teeth against the two distal faces of thefirst arm 22 prevented articulation about the fastener axis B, in theintermediate position, the curved portions of the first and second sideteeth 56, 58 may slide past the two distal faces 49 of the first arm 22allowing articulation about the fastener axis B.

[0030] The slots 60 in the first and second side teeth 56, 58 areconfigured such that rotation of the second arm 24 is generallyprevented when the second arm 24 is in the first slot position andarticulation is permitted when the second arm 24 is in the second slotposition. The slot 60 is of sufficient length to operate, in conjunctionwith the shape of the arms, such that the second arm 24 may be securedand released as described above.

[0031] With reference to FIG. 4-5, the embodiment of the presentinvention is shown in the access position. The above described rotationpermits the second arm to be articulated to the access position suchthat the second arm 24 is generally longitudinally aligned with thefirst arm 22. The second arm 24 remains in the second slot position withthe fastener 26 at the proximate end 64 of the slots 60. The proximateends of the first and second side teeth 56, 58 of the second arm 24 abutthe two distal faces 49 of the first art. These abutting surfaces,together with the fastener 26 contacting the slot 64 of the second arm24, prevent the second arm 24 from rotating beyond an approximately 180degree angle. FIG. 3 illustrates the second arm 24 forming anapproximately 90 degree angle with the first arm 22. FIG. 4 illustratesthe second arm 24, after articulation, forming an approximately 180degree angle with the first arm 22. The second arm 24 may be articulatedthrough any desired range of angles. The angles illustrated are includedas exemplary positions for the pull handle and are not intended to belimited to these exact positions. It will be appreciated that otherfasteners and other shapes of the first arm and the second arm may beused to obtain the desired movement of the dispensing handle.

[0032] The first and second arms 22, 24 of the pull handle arepreferably made from aluminum but may be manufactured from any othermetal, plastics, or any other suitable material that is capableembodying the required characteristics. The arms are preferably made bycasting. However, the arms may be formed using any suitablymanufacturing method. The arms are substantially rigid and of sufficientstrength to resist and/or withstand forces exerted on the arm from aplurality of directions.

[0033] With reference now to FIGS. 6-11, the operation of the pullhandle 20 is illustrated in connection with a dispensing machine havinga dispenser mechanism 68 and a dispenser door 70. FIGS. 6-8 illustratethe pull handle 20 in the dispensing position. FIGS. 9-11 illustrate thepull handle 20 in the access position. The dispensing machine is shownhaving two dispenser pull handles 20 embodying the present inventionconnected to dispenser mechanisms 68 (shown in FIG. 8) protrudingthrough openings 72 in the dispenser door 70. Door opening cover platesmay be mounted on the dispensing mechanism or the pull handle. The dooropening cover plate is preferably disposed against the opening, behindthe door, 70 by a spring, but may be held in place using any suitablemethod. The door opening cover plate may not pass entirely through theopening 72. The pull handle 20 may be pivotally coupled to thedispensing mechanism by a fastener 73 such as a screw, rivet, pin, bolt,or other suitable means for coupling the two arms. However, as can beseen in FIGS. 6-7, the length of the second arm 24 of the pull handle 20may be greater than the opening 72 in the dispenser door 70. Withreference to FIG. 8, if the door is opened in the indicated generaldirection 74 about a door hinge, the pull handles, in the dispensingposition, cannot pass through the openings in the door 70.

[0034] It should be appreciated that the joint where the pull handle 20is coupled to the dispenser mechanism 68 may be either in front of orbehind the opening 72 in the door 70. However, it is preferable thatsufficient distance exist between the second arm 24 of the pull handle20 and the door 70 of the dispensing machine such that the pull handlemay be engaged to activate the dispensing mechanism. In one embodiment,the distance between the second arm and the door and the length of thesecond arm is of sufficient length such that digital engagement of thepull handle 20 is not needed. In another embodiment, there is sufficientclearance between the door and the second arm, when in the dispensingposition, for a person's hand to fit in between the door and the handle.In another embodiment, the second arm is of sufficient length such thatthe handle may be engaged without a person's hand easily slipping offthe handle, and that the handle may be engaged with one hand and doesnot require the grasping or pinching of the handle. An exemplarydistance between the second arm 24 and the door 70 may range fromapproximately 0.4 inch to approximately 2.5 inches. However, anysuitable distance may be used. The pull handle 20 itself may not bedeterminative of this distance since the dispensing mechanism 68 mayextend through the opening 72 in the door 70 and increase the distancebetween the second arm 24 and the door 70. Conversely, part of the firstarm 22 of the pull handle 20 may extend within the dispensing machine70. Exemplary dimensions of the first arm 22 and the second arm 24 areapproximately 2.0 by 0.5 by 0.5, in inches. However, any suitabledimensions may be used. The longitudinal length of each arm, fromproximate end to distal end, may be of any length. An exemplary lengthis at least approximately 0.5 inch.

[0035] With reference to FIGS. 9-11, the second arm 24 is in the accessposition. It can be seen in FIGS. 9-10 that the pull handles 20 in theaccess position may have a cross-section width that is less than thediameter of the door openings 72. Therefore, the pull handle 20 may passthrough the door openings 72 when the door 70 is opened. FIG. 11illustrates a top view of the dispensing machine shown in FIG. 9 havinga partial sectional view of the door 70 in an opening position about thedoor hinge 76. As the door 70 opens about the hinge 76, the openingstravel in the indicated direction 78 in a circumferential path.Accordingly, the pull handles 20 may pivot at the joint to thedispensing mechanism permitting the pull handles 20 to pass through thedoor openings. It should be appreciated that the arms are generallyrectangular with cube-shaped bodies for the purposes of illustration.Alternatively, the main body of the arms may be cylindrical, oval, orrectangular, and the present invention may be embodied in any suitableshape or design as may be ergonomically and aesthetically desirable foruse.

[0036] In one embodiment, the length of the part of the pull handlebeing engaged, here, the second arm, does not depend significantly onthe size of the opening 72 of the door 70. Since the second arm 24 maybe moved from a dispensing position to an access position, the openingmay be smaller than the actual length of the arm being engaged. Forexample, the opening 72 need only accommodate the diameter or width of across section of the pull handle 20. Furthermore, the longitudinallength of the second arm 24 may be of any desired length. In oneembodiment, the longitudinal length of the second arm 24, from theproximate end to the distal end, may be greater than one-half thegreatest distance across the opening 72. In the embodiment illustratedin FIG. 6 and 9, the greatest distance across the opening 72 is thediameter of the opening, however, the opening may be of any otherdesired shape where the greatest distance across the opening may not bethe diameter.

[0037] The pull handle 20 embodying the present invention mayalternatively be used with objects other than dispensing machines. Forexample, any vending-type machine that requires a pull handle fordispensing may include a pull handing embodying the present invention.

[0038] The dispensing machine may be of any suitable configurationconsidering the product being dispensed, the location that thedispensing machine is being operated, and any other considerations. Inone embodiment, the dispensing machine includes a housing that isgenerally rectangular-box shaped. The rear of the dispensing machine maybe attached to a wall or other surface. The door 70 may be connected tothe housing with a hinge such that the door 70 may pivot open. Howeverthe door 70 may be attached to the housing in any suitable method. Forexample, the door 70 may be connected with locking latches or bolts suchthat the door may be entirely removed from the housing to access theinside of the dispensing machine.
